Volume has the appearance of distortion as shown in Figure 2 recklessly, or as shown in Figure 3, all bendings make front end be contacted with the appearance of skin H.The volume of this shape is K recklessly, successfully introduces the light maintenance that is installed in the net cutter and scrapes the hole difficulty.Because it is little to repair the opening of scraping the hole, scrapes weak point so that be suitable for introducing the front end of beard, therefore long volume is K recklessly, can not make it promptly to introduce.Successfully scraping disconnected long volume K recklessly for asking, the net cutter 101A that commonly uses electric razor shown in Figure 1 is equiped with the elongated hole 129 of slightly scraping.Slightly scrape hole 129, introduce volume Hu Eryu rapidly and scrape disconnected.Can successfully introduce volume recklessly though slightly scrape hole 129, can not be designed to make it to scrape to be broken into be short beard.Scraping disconnected volume recklessly with the net cutter 101A that slightly scrapes hole 129, is to scrape disconnected shortening in the position shown in the chain-dotted line of Fig. 2 and Fig. 3, makes its front end outstanding from skin H, and formation can be introduced and be repaiied the shape of scraping the hole.Scrape the volume K recklessly that is broken into this shape, be introduced in repairing and scrape the hole and scrape deeply and shorten.

Be recorded in the electric razor of aforementioned communique, as mentioned above, slightly scrape the hole and scrape disconnectedly, introduce in repairing and scrape the hole and scrape weak point, and scrape the hole slightly to scrape the hole and to repair in the installing of net cutter with Hou for rolling up recklessly to introduce.

But, be recorded in the electric razor of aforementioned communique, have and scraping the disconnected volume shortcoming of difficulty recklessly rapidly again effectively.This volume is cutter recklessly, scrapes volume deeply recklessly for asking, and must make the net cutter repeat to be contacted with skin and make repeatedly reciprocating motion.That is because scrape disconnected volume rapidly and have any problem recklessly slightly to scrape the hole.Volume is recklessly as slightly to scrape the net cutter in hole, scraped disconnectedly in the chain-dotted line position of Fig. 2 or Fig. 3, scrapes disconnectedly with Hou than the chain-dotted line position, scrapes short more difficult to repair the net cutter of scraping the hole.Scraped disconnected volume in the chain-dotted line position recklessly, can introduce rapidly to repair with Hou and scrape the hole and scraped deeply and shorten.

Slightly scrape the hole and repair the electric razor of commonly using of scraping the hole in net cutter installing, slightly scrape the hole and scrape disconnectedly, can not scrape disconnected volume effectively recklessly, must repeat to implement arch outside the past Hou of cutter along skin and move with the short time though volume can be introduced recklessly.

The present invention is that purpose is developed to eliminate this shortcoming, and free-revving engine of the present invention is to provide scrapes disconnected volume rapidly recklessly, can implement to scrape the electric razor of beard effectively again gallantly.

Electric razor of the present invention has the net cutter of the arch of being bent to, and, itself has to be installed so that the outer cutter of multiple row arch that can come in and go out with elasticity towards the skin direction of scraping beard and have the cutter edge of cutter inner face outside each arch and possess cutter in a plurality of arches that make the cutter inner face slip outside arch of this cutter edge.

And, electric razor of the present invention is slightly scraped cutter outside the arch with what slightly scrape the hole at net cutter opening, scrape repairing of hole and scrape cutter outside the arch with repairing at net cutter opening, constitute the outer cutter of multiple row arch, be not pushed on the state of skin, make and slightly scrape the outer cutter of arch and repair that to scrape the outer cutter of arch outstanding, can scrape disconnected volume effectively recklessly so that the net cutter in hole is slightly scraped in installing.That is electric razor of the present invention is not to set on same plane slightly to scrape outside the arch cutter and repair to scrape cutter arch outside, slightly scrapes the outer cutter of arch and repaiies that to scrape the outer cutter of arch outstanding but make, and scrapes disconnected volume Hu effectively and constitutes so that slightly scrape the outer cutter of arch.Repair scrape the outer cutter of arch outstanding slightly scrape the outer cutter of arch, can promptly scrape disconnected volume effectively again recklessly.Scrape disconnected volume recklessly slightly to scrape the outer cutter of arch, Hou scrape the outer cutter of arch and scrape deeply and shorten to repair.

The electric razor of this structure has and scrapes disconnected volume rapidly recklessly, can scrape the characteristic of beard effectively again gallantly.That is slightly to scrape slightly scraping arch outside cutter and scraping repairing of hole and scrape cutter arch outside a plurality of the repairing of net cutter opening of hole because this electric razor possesses in that net cutter opening is a plurality of, not being pushed on the state of skin, making with elasticity and slightly to scrape the outer cutter of arch and give prominence to be higher than to repair and scrape arch cutter outward.Outstanding be higher than repair scrape the outer cutter of arch slightly scrape the outer cutter of arch, when scraping beard, be contacted with skin really.Especially and skin concavo-convex, or hard part and soft part etc. it doesn't matter, repair scrape the outer cutter of arch outstanding slightly scrape the outer cutter of arch, be contacted with skin really, will roll up introduction recklessly and slightly scrape the hole and scrape disconnected rapidly.Scrape disconnected beard slightly to scrape the outer cutter of arch, be introduced into to repair and scrape the hole, scraped deeply again and shorten.The form of end in contact skin before electric razor of the present invention forms is preferentially scraped and disconnectedly is not easy very much to scrape disconnected volume recklessly with the outstanding higher outer cutter of arch of slightly scraping, and eliminates to leak and scrapes, and significantly shortens the time of scraping beard simultaneously.

Electric razor shown in the exploded perspective view of Fig. 4 and Fig. 5, possesses the outer cutter 1 of two row's arches that is installed in the electric razor body by coming in and going out freely, with the outer cutter 2 of the slit that is equipped on the outer cutter both sides of this arch, and be equipped on the outside of the outer cutter 2 of slit and three row combs 4 between the outer cutter 1 of arch, set the outer cutter shell 6 that outer cutter 1 of arch and the outer cutter 2 of slit are installed in loading and unloading freely with parallel, with loading and unloading freely the installing outer cutter shell 6 outer knife block 7, cutter 3 in the arch of sliding with the inner face that is pushed on the outer cutter 1 of arch, cutter 5 in the slit that slides with the inner face that is pushed on the outer cutter 2 of slit, with be connected arch in cutter 3 and the slit cutter 5 interior cutter platform 11 and make in cutter platform 11 reciprocating driving mechanisms (not shown).

Outer cutter 1 of two row's arches and the outer cutter 2 of two row's slits are shown in Fig. 6 exploded perspective view, by way station 6a, so that can be independent mobile towards distinguishing up and down, that is, so that can be installed in outer cutter shell 6, the outer cutter 2 of slit is adjacent to parallel the setting in the outside of the outer cutter 1 of two row's arches with coming in and going out.

The outer cutter 1 of two row's arches bends to arch with net cutter 1A and is fixed in plastic outer tool holder 1B.The outer cutter 1 of arch as slightly scraping the outer cutter 1a of arch, is scraped the outer cutter 1b of arch with the opposing party as repairing with a side.Slightly scrape the net cutter 1A opening of the outer cutter 1a of arch countless slightly scrape hole 29.Repair countless the repairing of net cutter 1A opening of scraping arch scraper 1b and scrape hole 30.

Slightly scrape hole 29 setting aperture areas and scrape hole 30, so that can successfully introduce recklessly by volume greater than repairing.And, slightly scrape hole 29 and set to repair and scrape hole 30 lengthwises, with the total length of long part, set to be longer than to repair and scrape hole 30.Slightly scrape hole 29 and make, so that can successfully introduce volume recklessly as elongated shape.Repairing and scraping hole 30 is to scrape short net cutter 1A through slightly scraping hole 29 to scrape disconnected beard, and its opening is just like roundlet or polygon.

The net cutter 1A that slightly scrapes the outer cutter 1a of arch is thicker than to repair the metallic plate of scraping the outer cutter 1b net cutter 1A of arch.Slightly scrape the net cutter 1A of the outer cutter 1a of arch, though do not need to scrape short beard since opening big slightly scrape hole 29, therefore make, so that have the intensity of filling part with thick metallic plate.Repair the net cutter 1A that scrapes the outer cutter 1b of arch and make, so that can scrape short beard with thin metallic plate.

And that slightly scrapes the outer cutter 1a of arch slightly scrapes hole 29, because opening is repaiied and scraped repairing of the outer cutter 1b of arch to scrape hole 30 long greatly again, therefore has the tendency of easy injury skin.Be anti-evils here, slightly scrape the outer cutter 1a of arch, net cutter 1A is made to be thicker than to repair scrape the outer cutter 1b of arch.If thickening net cutter 1A then when scraping beard, pushes the skin of slightly scraping hole 29 and becomes the inboard that is not easy to invade net cutter 1A.If skin is not outstanding from the inner face of net cutter 1A, cutter does not damage in promptly can not suffering.Because net cutter 1A makes beard protrude in inner face from slightly scraping hole 29, scrape disconnected with the interior cutter of slip inner face.Therefore, thick net cutter 1A slightly scrapes the outer cutter 1a of arch, and the skin injury that can prevent to scrape beard can prevent shouting pain.

Slightly scrape the net cutter 1A of the outer cutter 1a of arch, finger gauge is decided to be as 50～150 μ m, repair the net cutter 1A that scrapes the outer cutter 1b of arch, be defined as metal sheet as 30～100 μ m.The outer tool holder 1B of fixed network cutter 1A is a rectangle tubular at upper and lower opening with the plastics forming of hard.

The outer cutter 2 of slit as shown in Figure 6, knife plate 2A outside the fixed slit on the tool holder 2B outside plastic.The outer knife plate 2A of slit has a plurality of parallel slits 2a at metallic plate towards the extending transversely opening as shown in Figure 7 and Figure 8.The outer knife plate 2A of slit bends to top metallic plate as plane rectangular-shaped, extends to the vertical component effect opening parallel slits 2a in the outside from top and the bight outside.The skewed of parallel slits 2a width expanded in Fig. 7 and outer cutter 2 conducts of slit shown in Figure 8 towards the outside.The outer knife plate 2A of the slit of this shape has as comb and draws volume K recklessly in, makes it the advantage of introducing smoothly according to parallel slits 2a.

Fig. 9 represents the exploded perspective view of the outer cutter 2 of slit, and Figure 10 represents the ground plan of outer tool holder 2B.The outer cutter 2 of the slit of these figure is connected in outer tool holder 2B with the outer knife plate 2A of slit.The outer knife plate 2A of slit bends to the font with metallic plate, the two side lower parts installing of subtend mutually with outside the connecting portion 2b of tool holder 2B.Connecting portion 2b towards the below outstanding installing with the outside connecting portion 2c of the outside joint face 2e binding that is arranged on the outer tool holder 2B outside and be arranged on outside the inboard connecting portion 2d that is connected of the inboard joint face 2f of tool holder 2B inboard.Outside connecting portion 2c is installed in the two ends of the outer knife plate 2A of slit, and inboard connecting portion 2d is installed in the central portion of the outer knife plate 2A of slit.

Outer tool holder 2B is the square tube shape with the plastics forming.Outer tool holder 2B forms in central inner face with the two sides that outside joint face 2e forms in both ends with inboard joint face 2f.Because the outer knife plate 2A of illustrated slit, outside connecting portion 2c and inboard connecting portion 2d are installed in same plane, therefore outside joint face 2e is shaped as the step shape of low one-level so that can be inserted in the outside connecting portion 2c of the outer knife plate 2A of slit, inboard joint face 2f is inserted in inboard connecting portion 2d, be configured as the shape of the step that can be shaped in the inboard, so that the inner face of inboard connecting portion 2d and outer tool holder 2B is made same plane.

At outside connecting portion 2c and inboard connecting portion 2d installing through hole 2g, deviate from order to avoid be connected in the outer knife plate 2A of the slit of outer tool holder 2B, insert the hook protuberance 2h of this through hole 2g from outside joint face 2e and outstanding shaping of inboard joint face 2f of outer tool holder 2B.Insert the hook protuberance 2h of the inboard joint face 2f of inboard connecting portion 2d through hole 2g, be shaped as not from the outstanding height in inboard connecting portion 2d surface.Because if living reciprocating interior tool holder from the outstanding ， Ji Gao of inboard connecting portion 2d can not successfully move.

If the outside connecting portion 2c of the outer knife plate 2A of slit and outside joint face 2e and the inboard joint face 2f that inboard connecting portion 2d is connected in outer tool holder 2B promptly insert hook protuberance 2h at through hole 2g, the fixed position of tool holder 2B connects the outer knife plate 2A of slit outside.

Fig. 7 and slit shown in Figure 8 are made plane outward above the knife plate 2A general.Electric razor of the present invention does not need necessarily plane completely with making above the outer knife plate of slit.For example, also can make the radius of curvature of bending, make the general plane shape greater than the radius of curvature of the outer cutter 1 of the arch that bends to arch.

The thickness of the outer knife plate 2A of slit is thick than the net cutter 1A of the outer cutter 1 of arch, and for example 0.1～0.5mm preferably is set at 0.2～0.3mm, and 2～10 times of net cutter 1A preferably are set at about 5 times.The reason of the outer knife plate 2A of thickening slit is to widen the width of parallel slits 2a, the damage of minimizing skin H.To roll up Hu K as desire and successfully be guided in parallel slits 2a, must widen the width of parallel slits 2a.But, if widen the width of parallel slits 2a, promptly easily skin is pressed into herein, because of cutter 5 in the slit of slip inner face makes skin H damage easily.Be anti-evils here, the outer knife plate 2A of thickening slit.The outer knife plate 2A of thick slit as long as skin H is not pressed into parallel slits 2a depths, promptly can not make skin H damage because of cutter in the slit 5.

Widen the width of parallel slits 2a, be set at the outer knife plate 2A of the slit thick and scrape disconnected volume K recklessly reliably, and can reduce the damage of skin H than the net cutter 1A of the outer cutter 1 of arch.The outer knife plate 2A of the slit of the outer cutter 2 of slit slightly scrapes volume K recklessly.The volume of slightly being scraped is K recklessly, is repaiied with outer cutter 2 cutter 1 outside the arch that skin H moves of the slit that continues and scrapes.Scraped short volume K recklessly, scraped weak point again with the outer cutter 1 of arch.

Slightly scrape the outer cutter 1a of arch and scrape outer cutter 1b and the outer cutter 2 of slit, as shown in Figure 6, be installed in outer cutter shell 6, come in and go out with elasticity so that can distinguish independently with repairing.Slightly scrape the outer cutter 1a of arch and repair and scrape the outer cutter 1b of arch and outer cutter 2 usefulness the discrepancy of slit spring 16 and release with elasticity towards skin.The spring 16 of coming in and going out is to belong to helical spring pushing spring, with big stroke outer cutter 1 of arch and the outer cutter 2 of slit is pushed on skin.

The spring 16 of coming in and going out will be repaiied the floating pressure of scraping the outer cutter 1b of arch and be set at greater than the floating pressure of slightly scraping the outer cutter 1a of arch, in other words, more slightly scrape the outer cutter 1a of arch and will release to repair with elasticity more powerfully and scrape the outer cutter 1b of arch.Because it is little slightly to scrape the floating pressure of the outer cutter 1a of arch, therefore as Figure 11 and shown in Figure 12, scrape the outer cutter 1b of arch though surrender to be higher than to repair, if be pushed on skin, promptly repair and scrape the outer cutter 1b of arch for gently pushing.The electric razor of this structure is with the outstanding higher outer cutter 1a of arch that slightly scrapes of skin pushing, makes slightly to scrape the outer cutter 1a of arch and repair to scrape the outer cutter 1b of arch and be contacted with skin, can large tracts of land scrape beard effectively.And, also have so that slightly scrape the outer cutter 1a of arch and repair and scrape the state that the outer cutter 1b of arch is contacted with skin, will repair and scrape the outer cutter 1b brute force of arch and be pushed on skin, can scrape the advantage of short beard deeply.

Slightly scrape the outer cutter 1a of arch and scrape outer cutter 1b of arch and the outer cutter 2 of slit with repairing, at the state that is not contacted with skin, in other words, the spring 16 of will not coming in and going out is pushed on the state of compression direction, as shown in figure 12, will be by the outer cutter 2 of the slit in left side and repair three front end faces that are listed as outer cutter of scraping the outer cutter 1b of arch and scraping slightly that the outer cutter 1a of arch become, as with shown in the dotted line A, arrange in a straight line.The outer cutter of this figure makes and repaiies that to scrape the outer cutter 1b of arch outstanding than the outer cutter of the slit in left side 2, and, make and slightly scrape the outer cutter 1a of arch and to repair the outer cutter of the slit of scraping the outer cutter 1b adjacency of arch 2 outstanding.

The outer cutter of this figure makes that slightly to scrape the outer cutter 1a of arch the most outstanding, scrapes disconnected beard rapidly slightly to scrape the outer cutter 1a of arch.And the outer cutter of this figure is repaiied the difference of height (H2) of scraping outer cutter 1b of arch and the outer cutter of slit with slightly scraping the outer cutter 1a of arch and repair the difference of height (H1) of scraping the outer cutter 1b of arch, be set to be higher than.The outer cutter of this structure is pushed on skin with the state that slightly tilts with electric razor, makes the outer cutter of three row that is arranged in a straight line be contacted with skin together, can scrape beard effectively.

And, will make the electric razor posture that is contacted with skin, along with from the state court of inclination and the direction of skin quadrature, repair and scrape outer cutter 1b of arch and the outer cutter 2 of slit, the most outstanding outer cutter 1a of arch that slightly scrapes is contacted with skin reliably.Especially, owing to will slightly scrape the outer cutter 1a of arch and repair the difference of height of scraping the outer cutter 1b of arch, be set at greater than the outer cutter 2 of slit and scrape the arch difference of height of cutter 1b outward with repairing, therefore along with make electric razor from the posture that tilts to the vertical position banking motion, can preferentially will slightly scrape the outer cutter 1a of arch than other interior cutter and be contacted with skin.And, along with electric razor becomes posture with the skin quadrature, slightly scrape the ratio that the outer cutter 1a of arch is contacted with skin with making, make to repair and scrape the ratio that the outer cutter 1b of arch and the outer cutter of slit be contacted with skin and improve rapidly, scraping disconnected volume reliably recklessly.Therefore, contact electric razor with posture more, can scrape disconnected volume more effectively recklessly with the skin quadrature.

Make the front end of slightly scraping the outer cutter 1a of arch from repairing the outstanding difference of height of front end of scraping cutter 1b outside the arch, as 2～4mm, preferably about 2.5mm makes to repair and scrapes the outer cutter 1b of arch outstanding difference of height of cutter outside slit, as 1.5～3mm, preferably is set at about 2mm.

Slightly scrape the outer cutter 1a of arch and repair and scrape the outer cutter 1b of arch, the stroke difference of floating is pushed down to the position shown in the chain-dotted line.At this moment, come in and go out spring 16 by elastic compression.As shown in figure 12, slightly scrape the outer cutter 1a of arch and repair the front end face of scraping outer cutter 1b of arch and the outer cutter 2 of slit and come same plane with the state that is pushed down.Therefore, the unsteady travel settings that the outer cutter of this electric razor will slightly be scraped the outer cutter 1a of arch is a unsteady stroke of scraping the outer cutter 1b of arch greater than repairing, and, will repair the unsteady stroke of scraping the outer cutter 1b of arch, be set at unsteady stroke greater than the outer cutter 2A of slit in left side.Four exclusive cutter front ends come conplane plane, become the inclined plane that the right raises in Figure 12.Come conplane slightly scrape the outer cutter 1a of arch and repair scrape the outer cutter 1b of arch and the outer cutter 2 of slit can be scraped disconnected beard effectively with all outer cuttves of four rows.And, with the state that pushes most,, be not, but, have all outer cuttves, the advantage that can scrape beard effectively with four rows by posture contact slightly to tilt with right angle contact skin with the electric razor of four exclusive blade rows on the inclined plane.

As Fig. 6 and shown in Figure 12, four exclusive cuttves are installed so that can be displaced into outer cutter shell 6 up down.Therefore, slightly scrape the outer cutter 1a of arch and repair and scrape the outer cutter 1b of arch and the outer cutter 2 of the slit both ends of the surface installing slit 9 up and down of tool holder 1B, 2B outside, slit 9 guiding protrude in the guide protrusion 10 of the way station 6a inner face that is installed in outer cutter shell 6 up and down.

Four exclusive cuttves are installed in outer cutter shell 6 by way station 6a, so that can be by slit 9 and guide protrusion 10 move down up up and down.When four exclusive cuttves were independently mobile down up respectively, slit 9 moved down up along guide protrusion 10 up and down.

Repair that to scrape the outer cutter 1b of arch outstanding owing to slightly scrape the outer cutter 1a of arch, therefore as shown in Figure 6, the slit up and down 9 of slightly scraping the outer cutter 1a of arch is prolonged down up, surpass and repair the slit up and down 9 of scraping the outer cutter 1b of arch.The outer cutter 1 of arch of slightly scraping of long slit up and down 9 is pushed by spring 16 elasticity of coming in and going out, and gives prominence to be higher than to repair and scrapes the outer cutter 1b of arch.And, at Figure 11, be equipped on the outer cutter 2 of slit on right side, as shown in Figure 6, prolong down up than the outer cutter 2 of the slit in left side, longer than the length of the slit up and down 9 of outer tool holder 1B, cutter 2 outside the outstanding slit that is higher than the left side.

Four exclusive cuttves are because the elasticity of the spring 16 of coming in and going out is pushed out to the position that makes it to be contacted with guide protrusion 10 in the lower end of slit 9 up and down.In other words, the relative position of available up and down slit 9 and guide protrusion 10 is adjusted and is slightly scraped outer cutter 1a of arch and slit 9 and the slit extrusion position of cutter 2 outward up and down.

The way station 6a that four exclusive cuttves are installed in outer cutter shell 6 is inserted in the inboard of outer cutter shell 6 and fixes.As shown in Figure 6, way station 6a is made of with 3 connecting rod 62a that are connected this elastic plate 61a the elastic plate 61a that is positioned at two ends, and is integrally formed all with plastics.Elastic plate 61a connects in inboard installing and slightly scrapes cutter 1a arch outside and scrape outside the arch guide protrusion 10 of cutter 2 outside the cutter 1b and slit with repairing.

Elastic plate 61a is configured as the shape of being inserted in outer cutter shell 6 two ends inner faces with the shape in the outside.The hook protuberance 13 of the outer cutter shell 6 of lower end guiding of elastic plate 61a offers in order to avoid the through hole 14 that way station 6a breaks away from from outer cutter shell 6.And on elastic plate 61a, the connecting pin 8 of the spring 16 of coming in and going out is inserted in outstanding installing.

Connecting rod 62a establishes and is configured as lamellarly, is equipped between the four exclusive cuttves, connects top three places of elastic plate 61a.The connecting rod 62a of elastic plate 61a central authorities is outstanding towards the top than the connecting rod 62a of both sides, will be configured as comb shape above it.

Outer cutter shell 6 is by the end panel 61 that is positioned at two ends, and is connected these end panel 61 side faces at both ends plates 62 and becomes.The outer cutter shell that become with side panel 62 by end panel 61 6 is integrally formed as square shape with plastics.Outer cutter shell 6 is way station 6a to be inserted in inboard square shape.Side panel 62 is installed comb 4 in the above.The interval of comb 4 is formed and is wider than the interval of the parallel slits 2a of cutter 2 outside the slit.That is successfully to be guided in therebetween because will roll up recklessly.And comb 4 shown in Figure 8 makes leading section, and lateral bending is bent outstanding outwardly.When so that the posture that tilts when being contacted with skin, the comb 4 of this shape has and can arrange volume K recklessly effectively by protuberance, introduces the advantage of the outer cutter 2 of slit.

The position of comb 4 is at the state of releasing cutter 2 outside the slit with the spring 16 of coming in and going out, and in other words, the outer cutter 2 of slit is pushed on the state of skin, shown in the solid line of Figure 12, than being positioned at the below above the outer cutter 2 of slit.Cutter 2 is pushed on skin and is in the state that pushes most outside slit, and shown in the chain-dotted line of figure, comb 4 is made top same plane with the outer cutter 2 of slit with the upper end.Slightly scrape the outer cutter 1a of arch and repair and scrape the outer cutter 1b of arch and become and the outer cutter 2 same planes of slit at the state that is urged, the state that is not urged than slit outside cutter 2 outstanding.Therefore, slightly scrape the outer cutter 1a of arch and repair and scrape the outer cutter 1b of arch and the outer cutter 2 of slit and set freely being come in and gone out than comb 4 outstanding positions, scrape the outer cutter 1b of arch and the outer cutter 2 of slit and be pulled to the most down if slightly scrape the outer cutter 1a of arch and repair, promptly become and the same plane of the front end of comb 4.
